Mosquito, Tick & Fly Control for Ravalli County Homeowners
Mosquito Authority of the Bitterroot Valley is the only mosquito-dedicated service in the Bitterroot Valley, MT. While general pest companies treat mosquitoes as one line item among many, our entire program is built around a single goal: giving you your yard back. Service covers Mosquito Control, Tick Control, and Fly Control, with no long-term commitments required to get started.
The Bitterroot River corridor keeps standing water close to nearly every property in the valley, which means mosquito pressure doesn’t let up from late spring through early fall. Our treatments are timed to the mosquito’s breeding cycle, not a calendar. And if mosquitoes return between visits, we come back to retreat at no additional charge. That’s what No Mosquitoes. GUARANTEED. means.
Call (406) 446-8410 to get a free quote. No contract, no obligation.

Mosquito Authority of the Bitterroot Valley
Protecting Outdoor Living in the Bitterroot Valley
Montana’s outdoor season is short. Homeowners along the Bitterroot Valley floor invest in decks, patios, and backyards they want to actually use, but properties near the Bitterroot River, irrigation ditches, and low-lying meadows face heightened breeding conditions throughout the warm months. Standing water is never far away, and mosquito activity follows. Customers near the river describe season-long pressure that doesn’t ease until temperatures drop.
Whether you want one-time coverage for a specific event or protection across the full season, programs are built around your yard’s layout and your schedule. Morning patio time, family evenings in the backyard, weekends by the pool: those should work on your terms.
The 21-Day Treatment Cycle
Our service schedule is built around the mosquito’s breeding cycle. In the Bitterroot Valley, a new generation of mosquitoes can reach breeding age in as little as a few weeks. Our technicians return every 21 days to treat resting and reproduction areas before the next generation spreads across your yard.
If mosquitoes come back between scheduled visits, so do we at no additional charge. That’s what separates a mosquito-dedicated program from a general pest company making quarterly stops.
Get a Free Quote with No Commitment Required
A technician can walk your property, identify active breeding areas and resting spots, and outline the scope, approach, and price before any work begins. No contract, no long-term obligation. Call (406) 446-8410 or request your free quote online to get started.
How Mosquito Authority of the Bitterroot Valley Treats Your Property
Every visit follows the same four-step process because skipping any part of it leaves gaps that mosquitoes fill. They don’t breed in the open. They rest in shaded, moist areas during daylight hours: under leaf surfaces, in dense vegetation, and near any standing water. Finding those spots is the first step. Treating without inspecting is guesswork.
Property Inspection
Before any product is applied, your technician walks the property to locate active breeding areas and resting spots. Drainage patterns, vegetation density, and proximity to water all factor into where treatment needs to be concentrated.
Customized Treatment Plan
No two yards in Ravalli County are identical. Your plan is built around your yard’s specific layout and conditions, focusing coverage where mosquito activity is actually occurring rather than applying a standard blanket spray.
EPA-Approved Barrier Treatment
Treatment targets the resting and breeding zones identified during inspection. EPA-approved treatments safe for children and pets once dry are used throughout.
Scheduled 21-Day Return Visits
Your technician returns every 21 days to re-treat before the next mosquito generation reaches breeding age. Consistent, timed visits are what maintain protection across the season rather than letting populations rebuild between infrequent appointments.
Mosquito Season in the Bitterroot Valley, Montana
The Bitterroot Valley’s geography creates conditions that extend and intensify the mosquito season compared to drier parts of Montana. The Bitterroot River corridor, irrigated farmland, and low-lying meadows across the valley floor provide standing water habitat that supports active breeding from late spring through late summer. Snowmelt runoff in May and early June can push the season’s start earlier than homeowners expect.
Montana’s short warm season concentrates nearly all outdoor activity into the months when mosquito pressure is highest. West Nile virus has been documented in Montana, and while mosquito control isn’t a guarantee against disease, reducing your exposure by reducing mosquito populations is a straightforward precaution. The CDC consistently recommends avoiding mosquito bites as the primary defense against West Nile virus.
